  • Digital halftoning technique based on 1-D multi-scale dot assignment
    Patent number: 7580074
    Abstract: A line-based digital halftoning technique uses both a wavelet transform and multi-scale dot assignment concepts in which the dots are assigned in a top-down fashion and error diffusion is also adopted to fine tune the halftoned images and compensate for errors generated by the implicit quantization. 1-D processing makes the implementation easy while the top-down multiscale dot assignment can produce a multi-resolution halftoned image, which provides a good approximation of the original in multiple scales.
